Method of detecting relative risk for the onset of atopic dermatitis by gene single nucleotide polymorphism analysis

摘要

The present invention provides a method of discriminating a relative risk for the morbidity of atopic dermatitis of a test subject comprising: analyzing gene polymorphism of two or more of genes related to onset of atopic dermatitis using a sample isolated from a statistically significant number of normal persons and patients of atopic dermatitis to determine relative ratios (percentages (%)) related to the individual gene polymorphism of individual derived from the analysis; and calculating an odds ratio according to specified gene polymorphism from the relative ratio; and using, as a discrimination criterion, a combination of two or more of gene polymorphisms showing a synergetically higher odds ratio than odds ratios according to individual gene polymorphism. The method is useful for predicting susceptibility of an AD patient to chemicals based on genes and for selecting the diagnostic and/or therapeutic agent by eliminating harmful drug reactions from the analysis of principal factors related to onset and development of AD and interaction among these genes, and for determining a diagnostic method and therapeutic method using the detection method of morbidity risk.
